Arc Objects Spatial analyst Con Condition

Question

If inRaster < inputnumber1 Then outRaster = 1 ElseIf inRaster > inputnumber2 Then outRaster =0 ElseIf inRaster >= inputnumber1 and inRaster<= inputnumber2 Then outRaster = 0.5 * (1 + cos(3.14159*((inRaster– inputnumber1 )(inputnumber2 - inputnumber1 )))) Else outRaster = 0 The above statments i have to make in arcobjects by using spatial analyst.I am totally confused.Please help.How to make condition in IConditionalop of spatial analyst.Any help will be appreciated. Thanks in Advance. Regards

Hi

You can just get the pixels with direct read into array and use any calculation.

Check this: How to access pixel data using the RawBlocks object (ArcObjects .NET 10 SDK)

If you would use this Con statement manually in the Raster Calculator, it would probably look something like: Con(inRaster < inputnumber1, 1, Con(inRaster > inputnumber2, 0, Con((inRaster >= inputnumber1) AND (inRaster<= inputnumber2), 0.5 * (1 + cos(3.14159 * ((inRaster – inputnumber1) * (inputnumber2 - inputnumber1)))), 0))) Since you're using ArcObjects, things will get a bit more complicated to nest the Con Statements. Maybe you can find some useful info here: * ArcObjects 10 .NET SDK Help * ArcObjects Help for .NET developers
